The __Orange Pi 4__ is a single board computer uses the Rockchip RK3399 chip, and has 4GB LPDDR4 memory.


* __CPU:__ Rockchip RK3399 (28nm HKMG process); 6-core ARM® 64-bit processor ,main frequency speeds up to 2.0GHz. Based on the large and small size core architecture of big.LITTLE: Dual-core Cortex-A72 (large core) + Quad-core Cortex-A53 (small core)
* __GPU:__ Mali-T864 GPU. Supports OpenGL ES1.1/2.0/3.0/3.1, OpenVG1.1,OpenCL, DX11, support for AFBC
* __Memory + Storage:__ Dual 4GB LPDDR4 + 16GB EMMC Flash, Dual 4GB LPDDR4 +EMMC Flash(Default Empty)
* __On-board WIFI+Bluetooth:__ AP6256, IEEE 802.11 a/b/g/n/ac, BT5.0
* __Network:__ 10/100/1000Mbps Ethernet(Realtek RTL8211E)
* __GPIO:__ GPIO1 40 pins(1 x I2S, 2 x I2C, 1 x SPI/UART, 8 x GPIO), GPIO2 24pin PCIE port
* __Power Source:__ DC 5V/3A TYPE-C 5V/3A
* __OS Support:__ Android 8.1, Ubuntu 16.04, Ubuntu 18.04, Debian 9, Armbian 21.02.3
* __Dimension:__ 91.8x84.96mm


Note that the I2C 1 bus SDA and SCL pins do not reside on pins 3 and 5 like a Raspberry Pi, and so far despite there being multiple active buses (0, 1, 3, 4 and 7), I've been unable to get __any__ I2C device to show up using i2cdetect. Therefore, until there is some resolution of this issue, the Orange Pi is not considered suitable for robotics use. While it is a higher performance board than the [Raspberry Pi 4], it also runs very hot, with a power consumption of over 4 watts when fully loaded, whereas the Raspberry Pi 4 is rated 2.85w, the Pi 3 B+ at 2.5w. Testing on various websites indicates its actual power usage is probably closer to the Pi 4 when not using the neural processor of the Orange Pi 4B.
